  2. Tree rotation - Wikipedia

    en.wikipedia.org/wiki/Tree_rotation

    The rotation distance between any two binary trees with the same number of nodes is the minimum number of rotations needed to transform one into the other. With this distance, the set of n -node binary trees becomes a metric space : the distance is symmetric, positive when given two different trees, and satisfies the triangle inequality .

  3. Circular shift - Wikipedia

    en.wikipedia.org/wiki/Circular_shift

    Matrices of 8-element circular shifts to the left and right In combinatorial mathematics , a circular shift is the operation of rearranging the entries in a tuple , either by moving the final entry to the first position, while shifting all other entries to the next position, or by performing the inverse operation.

  4. Right rotation - Wikipedia

    en.wikipedia.org/wiki/Right_rotation

    In a binary search tree, a right rotation is the movement of a node, X, down to the right. This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child. This rotation is done to balance the tree; specifically when the left subtree of node X has a ...

  5. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.

  6. Rotation distance - Wikipedia

    en.wikipedia.org/wiki/Rotation_distance

    It can also be described as the shortest path distance in a rotation graph, a graph that has a vertex for each binary tree on a given left-to-right sequence of nodes and an edge for each rotation between two trees. [2] This rotation graph is exactly the graph of vertices and edges of an associahedron. [3]

  7. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    The two basic types are the arithmetic left shift and the arithmetic right shift. For binary numbers it is a bitwise operation that shifts all of the bits of its operand; every bit in the operand is simply moved a given number of bit positions, and the vacant bit-positions are filled in.

  8. CORDIC - Wikipedia

    en.wikipedia.org/wiki/CORDIC

    CORDIC (coordinate rotation digital computer), Volder's algorithm, Digit-by-digit method, Circular CORDIC (Jack E. Volder), [1] [2] Linear CORDIC, Hyperbolic CORDIC (John Stephen Walther), [3] [4] and Generalized Hyperbolic CORDIC (GH CORDIC) (Yuanyong Luo et al.), [5] [6] is a simple and efficient algorithm to calculate trigonometric functions, hyperbolic functions, square roots ...

  9. Finger binary - Wikipedia

    en.wikipedia.org/wiki/Finger_binary

    Finger binary is a system for counting and displaying binary numbers on the fingers of either or both hands. Each finger represents one binary digit or bit. This allows counting from zero to 31 using the fingers of one hand, or 1023 using both: that is, up to 2 5 −1 or 2 10 −1 respectively.
